Here is the code to show the image :

include "highgui.h"

include <iostream>

include <cv.h>

using namespace std; int main(int argc,char* argv) { char filename[]="0.jpg"; IplImage img = cvLoadImage(filename,CV_LOAD_IMAGE_UNCHANGED); if(!img){ cout<<"Error: Couldn't open the image file.\n"; } cvNamedWindow("Example1",CV_WINDOW_AUTOSIZE); cvShowImage("Example1",img); cvvWaitKey(0); cvReleaseImage(&img); cvDestroyWindow("Example1"); }

char filename[]="0.jpg"; How can it load an image without telling it the direct path of the image? or should I put my image in a default path?
